IMPROVEMENT IN ROVlNG-FRAMES.

Specification forming part of Letters Patent No. 34,753, dated March 25,186

To all whom it 11mg/ concern/.-

Beit known that we, JAMES HIGGINS, of Salford, in the county ofLancaster, Great Britain, machine-maker, and THOMAS SCHOFIELD WHITWORTH,of the same place, manager, have invented certain Improvements inMachinery or Apparatus for Preparing Cotton and other Fibrous Materialsfor Spinning; and we do hereby declare that the following is a true andexact description thereof.

Our invention relates to the slubbing or roving frame, and has referenceeither to machines in which a fixed tube is employed traversed by thecopping-rail or to those arrangements in which a tube moving with thecopping-rail isused and whereby an accommodation to any irregularity ofmotion is attained. f;

The first of these arrangements is shown at Figure 1, which representsthe tube and its spindle in elevation; and Fig. 2 is a partial plan viewof the same in section.

The spindle is shown at a, mounted in a fixed tube b-that is to say, atube which does not move upward or downward with the copping-rail. Thistube carries at the lower end the footstep c, which is mounted uponjoints d e, so as to swivel in directions at right angles to each other;but this part of the arrangement is not included in our presentinvention, it having been already made known by us. The copping-rail isat f, to which a bracket g is jointed by means of a pin 7i, so that thesaid bracket is free to turn upon or with the said pin as an axis. Theoutward end v1 of the bracket carries a boss k, which extends around thetube b and supports it at its upper part, and as it is carried by thecopping-rail it necessarily traverses the tube during the coppingmotion. The boss k is connected to the bracket g by means of a pin Z,which in this instance is a screw; but, as the shoulder thereof does notbear against it, it is free to turn or swivel thereon. As, therefore,the copping-ral runs and falls,

illust-rated at Fig. a.

it is at liberty to vibrate in two directions, the one being allowed bythe swiveling of the bracket in or upon the pin h, and the other by theturning or swiveling of the pin Z, and th us a tendency to binding isavoided.

The application of our invention-to those machines in which a tube moveswith the copping-rail is shown in sectional elevation at Fig. 3, andalso in partial plan view at Fig. 4. The spindle is shown at a, turningat bottom in a footstep c, capable of swiveling, or it may be a simplefixed footstep, if desired. The tube or bolster is at b, which in thisinstance is attached to the coppingrail f, and remains within the bobbinin the same position, and consequently moves bodily therewith during thecopping motion. The boss referred to in Figs. l and 2 is shown by thesame letter of reference `le, but in this case is attached to the tube.It is, however, provided with the bracket g, which is connected to thecopping-rail by means of a pin h, as above described in reference toFigs. l and 2, so thatthe tube is capable of swiveling, as beforementioned.

The tube b is provided with a shoulder upon which the bobbin-braidZrests, and this braid supports the bobbin, as usual.

We claim as our invention and as applied to machines in which a fixedtube is traversed to the copping-rail, causing the part which sotraverses to be capable of swiveling also in reference to machines inwhich a tube passes into the bobbin after the manner We claim- Soconnecting the said tube to the coppingrail that it shall be capable ofswiveling.
